After a 22-day absence from the football team due to personal reasons, Virginia Tech defensive tackle Corey Marshall was reinstated Tuesday.

Marshall, a 6-foot-1, 257-pound junior from North Dinwiddie, left the team Aug. 19 with scarce details provided about his departure. His availability for Saturday's game at East Carolina (2-0) is yet to be determined.

An e-mail sent Aug. 19 from Tech athletic director for football operations John Ballein said Marshall was "planning on taking some time away from the team to take care of some personal matters" and that his status with the team would be determined at a later date.

If Marshall is available this weekend, and if Hampton High graduate defensive end Tyrel Wilson is still dealing with a knee injury that kept him out of last Saturday's 45-7 win against Western Carolina, Marshall's versatility could be valuable.

Marshall volunteered in the preseason to move from defensive end to defensive tackle. Last season, he started four games at defensive end. As a freshman in 2011, he played mostly defensive tackle.

In addition to Marshall's return, Tech (1-1) also saw some personnel shifting Tuesday. Redshirt freshman Alston Smith, a Virginia Beach native who is the son of former Tech defensive end Bruce Smith, was moved from defensive tackle to offensive line.

On Monday, Tech coach Frank Beamer said he'd like to be able to redshirt offensive tackles Wyatt Teller, another converted defensive tackle, and Parker Osterloh, who is a Warhill High graduate. Both Teller and Osterloh are true freshmen. Alston's move to offensive line could help provide some needed depth.
